The failed intraperitoneal colon anastomosis after colon resection

The purpose of this study is to present the incidence of anastomotic leakage after colon resection and intraperitoneal anastomosis for colorectal cancer.

In the last ten years, 205 patients underwent colonic resection with intraperitoneal anastomosis for colon cancer. The surgical management of colorectal cancer consisted of 66 right hemicolectomies, 3 transverse colectomies, 17 left hemicolectomies, 98 sigmoid colectomies and 21 high anterior resections of the rectum. Diagnosis of leakage was made by clinical features, blood vessel examinations and abdominal CT-scans.

Anastomotic leakage occurred in 5 out of 205 patients (2.4%). One of these patients underwent emergency surgery and the other 4 elective surgery; 3 by manual, 2 by mechanical suture. Three patients with anastomotic leakage were reoperated on days 4, 5 and 7, and 2 patients were treated conservatively. Two of the patients (20%) with anastomotic leakage died due to sepsis.

Even though the rate of anastomotic leakage in patients with intraperitoneal anastomosis after colon resection for colorectal cancer is low, it remains a significant complication and a major cause of postoperative morbidity and mortality.
